Ditto pilot results

Replay bench of the Ditto router pilot. Each of the 36 sessions from Woolford's compaction study replication package (MIT) was turned into the compaction request Claude Code sends and passed through a fork of Ditto's router three ways: to Claude Haiku 5.5 and Claude Sonnet 5.5 as the default compaction model, and with the archetype route table on, which sends compaction to Microtensor's certified mt/ctx_compress.

compaction has one row per session with the session, the three summaries side by side, the arena grader's marks, the cost and the time. titles has the title request for each session; the Microtensor title route is a clearly labelled stand in (Qwen2.5 1.5B Instruct), not a certified model.

Code, relay logs and the method: https://github.com/microtensor-io/ditto-pilot
